But Trump is a strategist and rather than concede inevitable defeat he found a third choice: write an EO to stop this, tell congress "no bill needed, I fixed it" and then wait for the courts to overturn it. Then he can say "look, I told you this was never my idea. The courts and congress were making me do this and now they are again!" It's his best option.
Who is going to take it to court?
Where do you get the idea that President Trump is ignoring the law? CNN? MSNBC? Please explain yourself.
